Definitions
- the invention relates to a device according to the preamble of patent claim 1 and to a strip provided for this purpose.
- a first method uses a very complex one-way system, in which glued over said space and on the adjacent hatch cover edges a tissue tape which is destroyed when opening the hatches. Then, after each deletion of the cargo, resulting adhesive residues must be time-consuming removed from the hatch covers, in particular scraped off, so that when re-attaching such an adhesive tape a good adhesion is ensured. When scraping off adhesive residue, the coating applied to the hatch for corrosion protection is often damaged, which in turn also causes new unevenness and rust on the adhesive surfaces.
- Such a tape-shaped adhesive seal is previously known for example from JP 58-0 04 683 Y2.
- a second method utilizes a resilient rubber clamping profile which is clamped in the gap and braced between the hatch edges.
- a clamping profile requires that only seal gaps with almost the same and largely constant width and the surfaces to be sealed flat and smooth.
- this is particularly the case with older vessels due to wear and tear and plastic deformation. by no means always assured.
- Such clamping profiles are known in various designs and cross-sectional shapes, for example, as in-grooves inserted gaskets in DE 18 55 353 U, as a laterally lying U-shaped seals in JP 2004-0 51 073 A, as laterally cantilevered and superimposed strip-shaped Seals in JP 58-1 26 278 U, as wedge-shaped seals in JP 57-1 21 985 U, as rotatable multiple seals in JP 05-2 08 697 A and in the form of a gap bridging, U-shaped cover in the JP 06-0 16 178 Y2.
- the said gap is indeed in the dormant state of the ship, such as the charging process, about 10 mm in size.
- significant torsions of the hull and thus relative movements between the hatch covers and the hull, and thus between adjacent hatch covers may arise.
- DE 196 46 793 A1 mentions this as a measure up to a maximum of 40 mm.
- a seal must therefore be able to reliably seal a variable gap of 10 to 40 mm.
- the invention is based on the endeavor to provide a device with which said gap quickly, safely and, can be sealed repeatedly.
- a strip for realizing this device is to be specified.
- the invention therefore first proposes a device for sealing the gap between two adjacent hatch covers located at at least approximately the same height with at least ferro-magnetic hatch covers, which is characterized in that a flat, flexible strip is laid over the entire gap , whose width and length are greater than the width and length of the gap and the width of the space Ü-protruding outer longitudinal edges are placed on the adjacent hatch cover edges under magnetic force plan.
- the flexible strip used as a sealant provides good adhesion and sealing in rough ship operation and, even with frequent use, preserves the sealing surfaces of the hatch cover at the same time as it eliminates damage or contamination from adhesives or adhesive residue.
- Such a strip according to the invention can be used over and over again and can be securely attached and removed even by inexperienced assistants, and even in spite of rough handling.
- the flexible strip allows in particular to be transported, transported and stored during its removal from the intermediate space to a roll protecting the sealing surfaces. For use, the roll is then unrolled back over the gap and the strip is placed in its straight, magnetic-sealing form. The thus achieved fast assembly and disassembly of the seal leads to a reduction of expensive laytime of the ship.
- Slightly overhanging ends of the strip can be used for gripping in order to be able to loosen the strip from the hatch cover edges again conveniently and without any aids.
- the device for sealing can also be extended by bending the two end sections of the strip projecting beyond the length of the intermediate space downwards and pointing to downwardly pointing edge sections of the strip. the hatch cover are laid flat under magnetic force. Then the gap is also laterally, at its open ends, securely sealed.
- a hatch itself, and thus the hatch cover, from a ferro-magnetic material such. As steel.
- the invention can nevertheless be used, namely by applying a ferromagnetic layer to a non-ferromagnetic hatch cover edge and firmly connecting it to the hatch cover edge.
- a layer can be applied in very different ways and, for example, consist of a flat steel strip fixedly connected to the hatch cover edge or the like.
- Such a solid, permanent connection can then z. B. be made by gluing, screwing or riveting. The magnets of the strip then interact with their facing surface of the steel strip or the like.
- An embodiment of the device according to the invention can, in principle, take the form of a band-shaped strip.
- a strip for sealing the gap between two adjacent hatch covers on a ship is U-shaped in cross-section, and the free ends of the two U-legs are provided with magnetic means.
- the strip When using the strip, the U is upside down, d. H. the two U-legs point with their magnetic means comprehensive, free ends down to the respective hatch edge edge.
- Such a strip comprises in one embodiment a covering its entire width relatively wide and thin, flexible web strip and two at its edges with the web strip plane-fixed firmly connected, relatively narrow and thick leg strip.
- individual and a high magnetic adhesive force having magnets are arranged at a lateral distance from each other.
- the magnets may preferably have a flat roll or Rondenform and be arranged in recesses of the leg strip.
- Such recesses may expediently be designed as flat through holes or as blind holes whose shape and / or depth corresponds approximately to the shape and / or thickness of the magnets accommodated therein.
- the magnets do not need to form an outer partial surface of the leg strips, but are enclosed completely. There are different possibilities for this.
- through holes or blind holes are closed to the free outer surface of a leg strip of a relatively thin, but solid, and over the entire length of the respective leg strip and plane-parallel extending cover strip.
- Such a cover strip on the one hand should be as thin as possible to reduce the effect of the magnetic forces as little as possible, but on the other hand must be so thick or firm to transmit the magnetic pressure forces for secure sealing on the remaining strip.
- the thickness of a cover is thus also dependent on the material and can, for. B. amount to about one millimeter.
- An embodiment of the leg strip with through-holes can be made by extrusion and subsequent punching.
- the individual layers of the strip should be connected as firmly and permanently as possible.
- it can be provided in particular that at least two adjacent strips, such as web strips, leg strips and possibly covering strips, are glued or welded together.
- the material of the strip is adapted to the intended application. Durable strength and good flexibility can be ensured by, in particular, at least one of said strips being made of a vulcanized rubber and / or reinforced with fabric and / or made of a crenellated material, and / or of an extruded elastomer or thermoplastic or thermoplastic elastomer and / or made of a weatherproof and / or seawater resistant material.
- FIG. 1 shows a partial section through a first embodiment of a strip used in the device according to FIGS. 4 and 5, approximately on a scale of 1: 1.
- Fig. 2 shows a partial section through a second embodiment of a strip.
- Fig. 3 shows a portion of a leg strip of the strip of Fig. 1 in plan view.
- Fig. 4 shows a schematic representation of the plan view of a ship deck with two rows of juxtaposed, numbered hatch covers and central center covers.
- Fig. 5 shows the section V - V in Fig. 4, but on an enlarged scale, illustrating a space covered by a strip between two adjacent hatch covers.
- the flexible strip 1 With a length Ls of about 11.80 m, the flexible strip 1 has a use length adapted to the hatch length, which is considerably larger than the length of a gap to be covered and has in cross section, in principle, the shape of an upside down, folding symmetrical U.
- Er is composed of one of its entire width Bs of about 200 mm covering, flexible, about 3 mm thin web strip 2, the two edges 3, each with a parallel running, with about 40 mm width compared to this relatively narrow and about 6 mm thick leg strips 4 glued or welded.
- In each leg strip 4 are at intervals Am, see Fig. 3, of about 100 mm continuously recesses in the form of blind holes 5 are introduced, which are closed at the top of the edges 3 of the bonded web strip 2.
- the blind holes 5 have a circular diameter Dl of about 25 mm and a depth Tl of about 6 mm, so that between a blind hole 5 and the free outer surface 6, a material web 7 of the leg strip 4 of about 1 mm thickness is present.
- the total thickness Gs of the strip 1 is about 10 mm.
- roller or ronde-shaped strong magnets 8 are enclosed on all sides, wherein the magnetic effect i. W. perpendicular to the outer surface 6 towards running.
- the web strip 2 is reinforced by a central, not shown fabric insert.
- Fig. 2 is a partial view of a modification of the strip 1 is shown. Identical components are provided with the same, but with an indexed reference numerals.
- the modification refers to the illustrated leg strip 4 'of the strip 1'. This comprises here recesses in the form of through holes 5 ', the magnets 8' enclose and top of the web strip 2 'and bottom of an additional cover strip 9 are closed.
- the cover strip 9 occurs, so to speak, in the place of the material web 7 shown in Fig. 3 below the blind hole 5.
- the cover strip 9 is about 1 mm thick and permanently glued or welded to the leg strip 4 ', in turn, with the edge 3' of the web strip 'is firmly connected. Its outside forms the outer surface 6 ', which should act as a sealing surface.
- Fig. 3 shows a portion of a leg strip 4 of the strip 1 of FIG. 1 in plan view.
- the circular shape of the flat blind holes 5 with the diameter Dl of 25 mm and the depth Tl of 6 mm can be seen, which extend to the material web 7.
- the recorded therein and correspondingly shaped magnets 8 are shown in Fig. 1.
